How to make Neovim work with makefiles?

I have the following code structure:

And here’s the makefile:
_DEPS = event.h
_OBJ = event.o
_MOBJ = main.o
_TOBJ = test.o

APPBIN = event_time_app
TESTBIN = event_time_test

IDIR = include
CC = gcc
CFLAGS = -I$(IDIR) -Wall -Wextra -g -pthread
ODIR = obj
SDIR = src
LDIR = lib
TDIR = test
LIBS = -lm
XXLIBS = $(LIBS) -lstdc++ -lgtest -lgtest_main -lpthread
DEPS = $(patsubst %,$(IDIR)/%,$(_DEPS))
OBJ = $(patsubst %,$(ODIR)/%,$(_OBJ))
MOBJ = $(patsubst %,$(ODIR)/%,$(_MOBJ))
TOBJ = $(patsubst %,$(ODIR)/%,$(_TOBJ))
SRC = $(wildcard $(SDIR)/*.c)

$(ODIR)/%.o: $(SDIR)/%.c $(DEPS)
$(CC) -c -o $@ $< $(CFLAGS)

$(ODIR)/%.o: $(TDIR)/%.cpp $(DEPS)
$(CC) -c -o $@ $< $(CFLAGS)


Shorter names for convenience and more granular targeting

app: $(APPBIN)

test: $(TESTBIN)


$(CC) -o $@ $^ $(CFLAGS) $(LIBS)

$(CC) -o $@ $^ $(CFLAGS) $(XXLIBS) $(SRC) $(DEPS)
zip $(SRC) $(DEPS)

.PHONY: clean

rm -f $(ODIR)/.o ~ core $(IDIR)/~ $(SDIR)/~
rm -f $(APPBIN) $(TESTBIN)
rm -f

However, in the event.c file, neovim lsp keeps showing that some methods were not defined (in fact it was, in file event.h) as shown in the above photo. How do I config Neovim lsp so that it stops showing errors, because when I run make, there is in fact no error?


Have you solved this yet? I don’t actually know why it isn’t working for you, but I’m happy to try and help if it’s an issue you’re still struggling with.
